Pearl Jam fans who answered FaceTime calls from the rhythm guitarist got something extra for taking a vote-by-mail pledge — the latest offering from the band in a career full of activism and advocacy for political causes. Gossard offered free tickets to the next Pearl Jam show in that person’s city. “They were really happy when I told them I’d get them into the show,” the 54-year-old Gossard with a laugh. McCready and Gossard said Philadelphia has long been the home of Pearl Jam’s most fervent supporters. Gossard says his campaign promise of a few free tickets will be kept — as long their fans take the pledge.
